IMPROVED BLACKING-BRUSH.

The Schedule referred to in these Letters Patent and making part of the same.

To all whomit may concern Be it known that' I, RoBnIrIlAnAMs, of Cincinnati, in the county of Hamilton, and the State of Ohio, have invented a new and useful Improvement in Clamp- Irons for Blacking-Brushes, of which the following is a full and,clear description, reference being had to the accompanying drawings, making part of this specification. f

The nature of my invention'consists in the construction and arrangement of a ciampiIig-iron77 in connection with the blaeking-brush, by n'ieans of' which the blacking-,box may be readily replaced, or removed from beneath the spreading-brush.'

Figure l is an elevation of' ymy improved blackingbrush.

Figure 2 is a plan of the same.

Ineach of thegures, land 2, the red outline indicates the position of the spreading-brush when removed from over the' blacking-box. v

, A is-the polishing-brush, having'the handle a secured to the top of it.

`B is the blacking-box, located at one end ofthe brush A.

. C is the spreading-brush, concave on the nnderside, which alliiws of its closely fitting over the blackingbox B, v

` The arms b b, of' the clamp-iron D, are semicirc'ular, and, when in position, circumscribe the spreadingbrush C, to which they are firmly attached, at their extremities, by wood-screws c c.

The pivot-screw Eis iirmly secured in the inner` end of the handle af I t has a vertical position, and is passed through a perforation in the clamp-iron D, at the junction of the arms b b and lever-arm d.

A square nut, e, on the pivot-screw E, over the clamp-iron, is the bearing for the clamp-iron when it A is rotated.

The extreme end of lever-arm terminates in the: eye j, in which is tapped the thumb-screw F, which is of snticient length to enter the handle a.

Having described the construction-of my improved blacking-brush, l will now show its operation and advantages. l

In the accompanying drawings, the black outline Shows the brush in readiness for use.

W'hen the operator desires to remove a box which has been emptied, and to replace it with a full box, it

4is only necessary to give a few turns to the thumbscrew F, withdrawing it from the handle, (see iig. 1,) and mtatc the clamp-iron about the pivot-screw E, when the spreading-brush Gis removed from over the blacking-box B, whichv may be easily removed, and a frcslhhox placed in its stead. The spreading-brush is then returned to its place, and, by giving the thumbscrew a few turns, all the parts of the brush will be firmly retained in place, and the brush ready for use.

What I claim as new, and desire to secure by Letters Patent, is-v The clamp-iron D, having arms b b, and lever-arm d, the thumb-screw F, and pivot-screw E, or their equivalent, in combination with the spreading-brush C, polishing-briish A, and blacking-box` B, when the same are constructed, arranged, and operate as and for the pnrposeshown and described.`
